265k miles. Oil change and other PM stuff.
Air filter foam has caught a lot of crap in ~5000 miles. I find a wash in warm soapy water, rinse, and then a rinse with rubbing alcohol gets it nice and clean. Let it dry a bit and then reoil lightly.
The PCV catch can has been on for about 1500 miles and it caught an ounce of fuel-ish smelling oil stuff. Nice to see it's doing it's job and also nice to see that the crankcase isn't really generating much in the way of deposits.
